+[heading Description]
+
+`search_n` searches `rng` for a sequence of length `n` equal to `value` where
+equality is determined by operator== in the non-predicate case, and by a
+predicate when one is supplied.
+
+[heading Definition]
+
+Defined in the header file `boost/range/algorithm/search_n.hpp`
+
+[heading Requirements]
+
+[*For the non-predicate versions:]
+
+* `ForwardRange` is a model of the __forward_range__ Concept.
+* `ForwardRange`'s value type is a model of the `EqualityComparableConcept`.
+* `ForwardRange`s value type can be compared for equality with `Value`.
+* `Integer` is a model of the `IntegerConcept`.
+
+[*For the predicate versions:]
+
+* `ForwardRange` is a model of the __forward_range__ Concept.
+* `BinaryPredicate` is a model of the `BinaryPredicateConcept`.
+* `ForwardRange`'s value type is convertible to `BinaryPredicate`'s first argument type.
+* `Value` is convertible to `BinaryPredicate`'s second argument type.
+* `Integer` is a model of the `IntegerConcept`.
+
+[heading Complexity]
+
+Average complexity is Linear. Worst-case complexity is quadratic.
